VERY BAD SERVICE FROM FNB

I have done a online purchase with pc link which gone bad. So i asked fnb ***** line to help. They asked certain document which I have sent and waited for a response. This was on the 21 April 22. Did not get any reply from them so decided to call. The agent helping was nice and helpful in escalating the problem to the person who had helped me the first time. No response. So i called again days later spoke to her supervisor which put me on hold for 45min.... i had to endure painful music in that time not once the supervisor came back to apologize for the long wait. I had to put the phone down after 45min. Still no call back to apologize. Still no answer to my query.... so days later again called the complaint department well that was n waste of time. They tried to call the agent that handled the case. No answer but spoke to someone else. She escalated the problem again instead of trying to resolve. So if one of the biggest banking institutions is handeling my/your money or problems so bad I foresee a very dark future for banking. If i could give minus stars for service i received i would have. Not happy at all
